10 More Years for the ISS
 
Feb. 14, 2014: A lot can happen in 10 years. Over the past decade an
international laboratory, widely known but often under-appreciated, has been
producing results at an extraordinary rate. Using its unique capabilities,
engineers have developed a precision robotic arm that helps surgeons remove
tumors from the human brain; experimenters have learned to start fires without
flames-an anti-intuitive technology that could lead to super-efficient auto
engines; physicists have counted hundreds of thousands of anti-matter
particles among normal cosmic rays, a telltale sign of mysterious dark
matter.; researchers have gathered atoms into exotic forms, creating the
building blocks of futuristic smart materials; .and much more.
 
That lab is the International Space Station.

"The accomplishments of the past 10 years are remarkable--especially
considering that the space station was still under construction." notes Julie
Robinson, program scientist for the ISS. "Now that the station is finished,
we've been granted at least 10 more."
 
In January, the Obama Administration announced an extension of the
International Space Station until at least 2024.  The extra time allows NASA
and other space agencies around the world to pursue a number of important
goals.
 
For one thing, the ISS is crucial for long-duration travel through deep
space.  "That may sound ironic given that the space station never leaves Earth
orbit," says Robinson, "but we have determined that research on station is
necessary to mitigate 21 of 32 known human-health risks associated with long
duration space missions. The road to Mars leads through the ISS."
 
She adds that medical research for astronauts helps people on Earth, too.
Treatments for bone loss and muscle decay, and advances in telemedicine are
just a few of the spin-offs that have made their way into hospital rooms since
the ISS program began.
 
As the next ten years unfolds, a menagerie of "model organisms" will join
astronauts on the ISS for advanced life science studies.  New "crewmembers"
include weeds, fruit flies and rodents-all of which share surprising amounts
of DNA with humans. "By studying these organisms in microgravity, we will
learn a lot about ourselves," she says.
 
Although Robinson has a degree in biology, some of her favorite experiments
are in the area of fundamental physics.  For instance, she says, "the
station's Alpha Magnetic Spectrometer program, led by Nobel laureate Samuel
Ting, is poised for breakthroughs on the nature of dark matter." Another
exciting project is the Cold Atom Lab, slated for flight in 2016.  "We are
going to create the coldest spot in the known universe inside the ISS," she
says.  "This will allow researchers to study exotic forms of quantum matter
such as Bose-Einstein condensates."
 
With the "big blue marble" looming large in its window, the space station is a
powerful platform for Earth science. Sensors under construction and slated for
launch in the next few years include instruments for hurricane forecasting,
studies of the global climate, and lightning hazards.  "The extension of the
space station allows Earth science instruments to collect longer term
datasets," notes Robinson.  "Some of our existing sensors will collect 90%
more data during the extra decade."
 
The station's 10-year extension also boosts the development of America's
homegrown commercial space program. SpaceX and Orbital Sciences Corp., which
have contracts to supply cargo to the station, can now look forward to
competing for future contracts. SpaceX, Boeing and Sierra Nevada are also
interested in launching crews to the station by 2017. As commercial providers
provide access to Earth orbit at lower cost, we move toward the day when
scientists will travel to space to do their own experiments, first-hand.
 
Ten more years, indeed.  For more information about research on the
